Platform Notes:The eri FastEthernet Device Driver

Configuring the Host File

The 64-bit driver is included with the Solaris CD.

Before using eri as your network interface, you will need to create and edit system host files, as described in the next section.

To Configure the Host File

  1. At the command line, use the grep command to search the /etc/path_to_inst file for eri devices. For example:


    # grep eri /etc/path_to_inst
"/pci@8,700000/network@5,1" 0 "eri"

  2. Create an /etc/hostname.erinum file, where num is the instance number of each interface you plan to use.

    If you want to use the network interface from the example in Step 1, you will need to create a file:

    File Name 

    Instance Number 

    /etc/hostname.eri0

    0 

    • Do not create /etc/hostname.erinum files for Sun eri FastEthernet network interfaces you plan to leave unused.

    • The /etc/hostname.erinum file must contain the host name for the appropriate network interface.

    • The host name should have an IP address that will need to be entered in the /etc/hosts file.

    • The host name should be different from any other host name of any other interface, for example: /etc/hostname.hme0 and /etc/hostname.eri0 cannot share the same host name.

    Using the instance examples in Step 1, the following example shows the two /etc/hostname.erinum files required for a system called zardoz that has a Sun eri FastEthernet (zardoz, zardoz-11). 


    # cat /etc/hostname.hme0
zardoz
# cat /etc/hostname.eri0
zardoz-11

  3. Create an appropriate entry in the /etc/hosts file for each active eri network interface.

    Using the previous example, you will have: 


    # cat /etc/hosts
#
# Internet host table
#
127.0.0.1     localhost
129.144.10.57 zardoz    loghost
129.144.11.83 zardoz-11

    Note -

    The Internet Protocol, version 6 (IPv6), expands the capabilities of IPv4, which is the current version and the default. The Sun eri FastEthernet device driver included in this release of the Solaris operating environment supports both IPv4 and IPv6. IPv4 uses the /etc/hosts configuration file, but IPv6 uses a different configuration file. To transition to, manage, and implement IPv6, refer to the Solaris 8 System Administration Guide, Volume 3.

  4. Reboot your system.
